Meanwhile, the supporting piece 11 is provided with a plurality of vacuum suckers which can suck the tray 7 arranged on the supporting piece 11, so that the supporting of the tray 7 is more stable and firm.
Referring to fig. 2 and 3, the tray support mechanism 14 has two, one of which is mounted on the table plate 51 by a bracket and is located outside one end of the opening 511; the other is erected above the opening 511 through a bracket; the two tray support mechanisms 14 are symmetrically arranged. A baffle 16 is provided between the two tray support mechanisms 14, and the baffle 16 is bridged over the opening 511. The palletising station 101 of the pallet 7 is formed between the blind 16 and the pallet support mechanism 14 mounted on the work top plate 51.

Referring to fig. 2 and 4, the robot 15 is mounted on the table plate 51 outside the end of the opening 511 remote from the tray support mechanism 14. The robot arm 15 includes a plurality of first suction nozzles 151, an optical fiber sensor 152, and a horizontal multi-joint robot 153. The plurality of first suction nozzles 151 are divided into two groups and are respectively coupled to the action shaft 1531 of the horizontal multi-joint robot 153 by brackets. The first suction nozzle 151 is movable above the opening 511 by the driving of the horizontal articulated robot 153; the position corresponding to the part of the opening 511 located below the first suction nozzle 151 at this time is defined as the material transfer position 102 of the tray 7. Meanwhile, the positions of the two sets of first suction nozzles 151 can be adjusted by driving the action shaft 1531, so that the two sets of first suction nozzles 151 can simultaneously suck the materials in the two adjacent material grooves 71, thereby realizing the operation of sucking two pieces of materials at a time. In addition, the optical fiber sensors 152 are provided with two optical fiber sensors, which are respectively arranged beside the two groups of first suction nozzles 151 and used for detecting whether materials exist in the tray 7 or not and preventing the first suction nozzles 151 from being sucked in an empty mode.
Referring to fig. 4, the tray fixing mechanisms 17 are symmetrically disposed outside the long sides of the opening 511, and are adjacent to the material transfer positions 102 of the tray 7. The tray fixing mechanism 17 is similar in structure to the tray supporting mechanism 14, and includes a second driving cylinder 171 and a second fixing member 172; wherein, the second driving cylinder 171 is erected outside the long side of one side of the opening 511 through a bracket; the second fixing member 172 is a fixing plate, one side surface of which is fixedly connected to the piston rod of the second driving cylinder 171, and the other side surface of which faces the material-moving position 102 and is provided with a plurality of clamping blocks. Through the drive of second drive cylinder 171, the fixed plate can laminate the side of tray 7, and the fixture block joint is in the recess of tray 7 side. The tray 7 can be held and fixed by the opposing action of the two tray fixing mechanisms 17. In order to increase the fixing of the tray fixing mechanism 17 to the tray 7, a supporting plate extending to the material shifting position 102 may be additionally installed at the bottom of the second fixing member 172 to support the bottom of the tray 7.
Referring to fig. 4, a plurality of material shifting steps 18 are arranged at the material shifting position 102 of the tray 7; the kick-off steps 18 are each bridged over the opening 511 by a brace, and the step 181 of each kick-off step 18 is in an inverted position (i.e. step facing down). Two material shifting steps 18 form a group, and each group of material shifting steps 18 corresponds to the material groove 71 one by one. When the tray 7 is located at the material-shifting position 102, the two material-shifting steps 18 belonging to the same group are symmetrically located at two sides of the corresponding trough 71, and the step part 181 of the material-shifting step 18 extends to the upper part of the trough 71. The kick-off step 18 serves to prevent excess material being carried over due to material sticking. When the first suction nozzle 151 sucks the material out of the material groove 71, the edge of the material touches and is shifted by the step part 181 of the material shifting step 18; because the material has elasticity and flexibility, the material sucked by the first suction nozzle 151 is restored after being stirred by the step part 181, and another material adhered below the material due to static electricity is stirred and falls back into the material groove 71.

S106, the linear driving piece 13 is started again to drive the supporting piece 11 to return to the stacking position 101; then piston rods of double-layer cylinders of the upper and lower driving parts 12 are ejected out, so that the supporting parts 11 are propped against the stacked tray 7 from bottom to top; thereafter, the first driving cylinder 141 retracts, thereby releasing the support of the tray 7 by the tray support mechanism 14; the piston rod of the lower cylinder 122 retracts, the supporting part 11 descends, and the stacked tray 7 integrally moves downwards, so that the tray 7 originally positioned at the second bottom layer is changed into the bottom layer tray 7.
S107, while S106 is performed, the robot 15 is activated, and the first suction nozzle 151 sucks out the material in the tray 7 and transfers the material to the first mobile carrier 351 located at the first near-robot point 353.

In this way, the material is sequentially detected by the first detecting means 32, the second detecting means 33, and the third detecting means 34 from the first relay mechanism 35, and then transferred to the second relay mechanism 36. Since each second suction nozzle 315 of the carrying mechanism 31 can only suck one piece of material at a time, the first mobile carrier 351 can carry two pieces of material at a time; therefore, after the first piece of material is removed, the first mobile carrier 351 moves on the first carrier moving module 352 to match the position of the second suction nozzle 315. The second mobile carrier 361 is also used.
And S3, collecting materials, wherein the step is similar to S1.

S308, when the material tray 7 is filled with the material, the tray fixing mechanism 17 releases the fixing of the tray 7, and the two material forks 62 hold the tray 7 and descend into the table 52. After the next tray 7 is filled, the fork 62 is raised again so that the tray 7 is stacked on the tray 7 on the fork 62; the circulation is carried out, and the trays 7 filled with the materials are stacked together; when the predetermined number of pallets has been palletized, the two forks 62 are lowered and the palletized pallet 7 is placed on the horizontal conveyor belt 63; the horizontal conveyor belt 63 is started to send the stacked trays 7 to the tray carrier 64; the operator takes out the tray vehicle 64 to finish the material collection of the qualified materials.
